The primary function of this system is to add extra air into the cylinders during the first 20-30 seconds of cold start up to lean out the mixture a bit and heat up the catalytic converters so they work more efficiently.

Thanks for being exactly that.. Lol but yes I have been reading for the last hour and have found my answer. I was just being lazy and didn't want to go through 30 pages of post's. Just trying to save time, I'm sure you understand.

I really didn't think a yes or no answer would be such a big deal. lol but whatever someone mentioned that it your valve is stuck closed to just delete the codes and move on. If I did this would my car mess up in any way?

My 2006 Impreza wrx just threw these codes at me a p2440 and p2442.My cobb accessport says its my secondary air injection valve bank one and bank two are stuck open. I dont know what they are could someone please tell me if these are harmful to my engine and should be fixed very soon or is it alright just to clear them with my accessport?

Just an update for my car.
Had the P0410 code, and I will conform that it is just the air pump itself that has gone bad. I bought a used pump off a nasioc member and its just fine now. Next time I have a problem... delete plates are going on.
